從 Visual Studio 複製程式碼貼到 Word/Outlook/PowerPoint 時保留顏色標示是很常見的需求。很久以前 VS2010 剛推出時複製貼上中文有個 Bug，我還寫了土砲工具解決呢。(謎之聲：可以不要一直想當年嗎？) 之後它一直是 VS 的內建功能，但到 VS2017 時似乎被拿掉，所幸我找到 Microsoft DevLabs 寫的 Copy As HTML 套件上場救援 (Copy As HTML 也含在 Productivity Power Tools 2017/2019 裡)，使用起來倒也沒啥問題。

但從某個 VS2019 版本起，複製程式碼時常會導致 Visual Studio 凍結沒反應，爬文發現我不孤單，停用它複製功能才恢復正常。

忍受貼黑白程式碼或改從 VSCode 複製好一陣子，今天決心找出解法。爬文發現 Visual Studio 有個很少人討論的選項：(我查到最的討論在 2019，說不定一開始就存在)

啟用 「Copy rich text on copy/cut」後，VS2019 就能複製貼上彩色程式碼了，至於下方的「Use accurate classifition」選項，官方文件沒提供 Advanced 類設定的說明，我只在這篇 Copy and paste C++ source into Word loses formatting 討論找到微軟 RD 的回覆：

Language services typically provide 2 kinds of colorization – quick syntactic colorization and rich but slower semantic colorization (e.g. user types). This way a newly opened file is already colorized based on syntax, but once semantic information becomes available, richer colorization appears. So when this checkbox is checked, Copy/Cut commands would copy accurate, final colors even if calculating those would take more time (a wait dialog will be shown after 2s).
The document for the Tools/Options/Text Editor/Advanced page are in progress....

大意是 Language Service 提供快速及完整兩種語意色彩標示，勾選「Use accurate classifition」會等待完整色彩標示 OK 再複製，會多等個兩秒。(另外也有提到 Advanced 部文件來不及寫的事)

不過 VS2019 複製貼上的程式碼一律採用白色背景(不管 IDE 是否設定深色主題)，適合 Word/Outlook；若想沿用深色背景樣式放在深色底投影片上，可考慮改用 VSCode，或用 Copy As HTML 套件加自訂樣式[參考]。

最近也會先貼到Notepad++ 先用 設定>設定程式語言格式>選取主題(挑順眼的) 再用 外掛>NppExport>Copy all formats to clipboard 有點麻煩但熟悉之後可變性很高XD
